What is your favorite level for clank, ratchet and qwark?
Mine are:
Ratchet: Exercise Yard
Clank: Asyanica
Qwark: The first one, can't remember the name

clank: mine are actually one of the special missions where you have to get all the rings with the car AND can do 2 wheels and roll overs! quark:madam buttrquark and the first one <larger than life>
and ratchet:the one where you stop the breakout.

for clank i like the rythm dance mission
for the gagebots i like the ones where you have to figure out how to power all of the colums
for ratchet i like the first extra mission in the tree house
for quark i like the space nuns misison

clank:asyanica and giant clank mission
ratchet:the showers
quark: madam butterquark
gadgebot: asyanica

I've changed my mind - for Ratchet my favourite is probably the last one - the Prison Escape
